SASH-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 601,959, dated April 5, 1898. a

Application filed November 1, 1897. Serial No. 656,990. (No model.)

To all whom it may concern;

Be it known that I, ADOLPH HAENICHEN, a citizen of the United States, residing in Paterson, county of Passaic, and State of New Jersey, have invented certain new and useful Improvements in Sash-Fasteners; and I do hereby declare the following to beafull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to provide a combined sash balance and fastener of simple, strong, and durable construction and by means of which the sash is held in any desired position and when fully down or closed securely locked.

The invention consists in the improved sash balance and fastener and in the combination and arrangement of the various parts thereof, substantially as will be hereinafter more fully described, and finallyembodied in the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several views, Figure 1 is an inside elevation of a portion of a window-frame provided with my improvement, certain portions being broken away and others removed to better illustrate the nature of my said invention; Fig. 2, a sectional view on the line so 00 of Fig. 1, and Fig. 3 a front elevation of the sash balance and fastener and of the adjoining portions of the windowframe.

In said drawings, arepresents the windowframe, and b and c the lower andupper sashes, respectively. One side of each of the said sashes is provided withan elongated groove d, in which is secured a barf, provided with a series of triangular-shaped teeth g, having their lower surfaces arranged substantially horizontal and also provided at its upper portion with a projection h, the top surface of Y which is also horizontal.

with its outer end to the covering-plate m and carrying at its free end a bolt 19, penetrating an opening in said plate m and adapted to engage the top surface of the projection h and the lower surfaces of the teeth g, respectively, as will be hereinafter more fully described. To about the center portion of said springplate 0 and at right angles thereto is secured an arm or lever-q, penetrating an opening m in the covering-plate m and an opening a in the stop-bead a of the window-frame and is provided at its free end with the thumbplate q and adjacent thereto with the notch (1 Said notch g is adapted to be engaged .by'a fulcrumed pawl 1" when the said arm g has been pressed inward to withdraw the bolt 10 from the toothed rack-bar f, thus allowing the sash to be moved up or down.

When the sash is fully down or closed and the bolt 10 engages the upper surface of the projection h of the bar f, said sash is prevented from being opened, except when the arm q is pressed inward and the said bolt is withdrawn.

, When the sash is to be raised to a certain height, the arm (1 is pressed inward, and after the sash has been adjusted to the heightrequired the said arm is again'released. The bolt 19 then engages the lower surface of its respective tooth g and holds the sash firmly in the desired position.

When the sash is to be closed, the arm qis again pressed inward and held in said position until the said sash has reached its lowermost position.

It will be manifest-that the arrangement of I the parts on the upper sash is similar to that on the lower sash, but preferably the bolt and arm are arranged at or near the lower portion of said sash, so that they can be conven iently operated.

It will be manifest that my improved sash balance and fastener can be used in connection with sash-weights, if so desired, thereby facilitating the raising of the said sash.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination with a vertically-movable sash and with the window-frame respectively having teeth and a socket oppositely arranged sash, to operate the spring, and a lockingpawl pivoted to said bead and adapted to engage the notch in said lever, substantially as r5 described.

In testimony that I claim the foregoing I have hereunto set my hand this 12th day of October, 1897.

ADOLPI-I HAEENICHEN.
